Maybe 1.6A is the peak when it spins up and 1.25A is the regular consumption. Well, we made the experience that these values provided by fan manufacturers are quite often pretty wrong so I would not trust these numbers too much.
The poweradjust can handle short peaks of up to 4.5A so that should be enough for these fans.
You were right right there, 1.6 peak for spin up, the 1.25 draw. Basically one poweradjust can power 2 of these without heatsink.
Thats why i got 6 of them without heatsink for now, im going to get the red version that will work with the front mounting plate, when its going to get out.
You sad its going to be weeks, Any ideea if its going to get out by the end of the year? or is it going to be next year ?
